It should be possible to discover the existence of extraterrestrial technological civilization by detecting CFCs and other greenhouse gas emissions unnatural it would have used to terraform an exoplanet. printable coloring pages For this, it is sufficient to analyze the composition of its atmosphere with the James Webb Space Telescope (JWST) or its successor.
